JAMES INGRAM, OF NEW YORK, N. Y.

WATER-BACK FOR COOKING-RANGES.

Specification of Letters Patent No. 31,083, dated January 8, 1861.

To all whom it may concern:

Be it known that I, JAnns INGRAM, of.

the city and State of New York, have invented and made certain new anduseful Improvements in Fitting Water-Backs for Cooking-Ranges, &c.; andI do hereby declare that the following is a full, clear, and exactdescription of the nature of my said invention, reference being had tothe anneXed drawing, making part of this specification, wherein Figure 1is a plan of a cooking range with a portion of the top plates removed toshow the water back in place, up to the fire; Fig. 2 is an elevation atthe back of the range, and Fig. 3 is a cross section of the range withthe brick or soapstone intervening between the water back and the fire.

Similar marks of reference indicate the same parts.

My present invention is an improvement upon Letters Patent granted to meFebruary 16th, 1858, and consists in an improved manner of mounting,fitting, and actuating the water back, whereby the same can be movedwith greater facility than in my said previous patent and greaterconvenience is furnished for introducing the soapstone or fire brick orremoving the same so as to bring the water back to its place against thefire. In my aforesaid patent the movement of the water back was allowedfor by the spring of the pipes; but I soon discovered that too muchpower was required for moving the back against the stiffness of thepipes. I therefore provided hollow or faucet hinges on which to movesaid water back, in order that the said hinges might allow for theturning of the water back up to or away from the fire; and to compel theservant or other person who moves the water back to give the properamount of motion to bring the water back up to its place I provide apendent finger that prevents the covering plate going on until the backis properly in place.

In the drawing a is the top, I), the front and (Z the back of anyordinary range or stove; c, is the fire place, and e, is the water back.

and g are the circulating water ipes I connected to the water back bythe coup ings the water back can be moved up to the fire as in Fig. 1,or away from the same as in Fig. 3. The weight of the water back restson the rollers 2, that run on the flanges 3, that project from the sideplates of the stove or range, so that said water back moves with butlittle power. it, is a lever that I employ for moving said water back;said lever is set on a fulcrum 5, and connected to the water back by thelinks 4, 4c'th'e upper part of the lever being formed as a fork to passthe pipes f and g and the joints being quite loose, so as to allow forthe swinging movement of the water back.

i, is a sliding bar passing througha hole in the plate 7 and having anotch at 6, to

drop behind said plate 7 and keep the water back forward when saidsliding bar is pushed in. A hole at the end of this bar 2', serves forreceiving a poker by whichit is moved.

7c is a plate setting over the water back (see Fig. 3 and plan Fig. 4)to exclude dust and heat from the chamber in which it moves and Z, is aplate setting into the top plate a, and level with the surface thereofand 10, is a flange pendent from said plate, which flange sets down tothe top of the water back and has a projecting finger 8, passing througha mortise 9 in the plate is, the object of this finger being to insurethe water back being properly forward or sufficiently back, or else theend of this finger resting on the water back would prevent the plate Z,going down to its place, thus insuring a proper movement of the waterback even in the most careless or inexperienced hands.

lNhenever any cause occurs, such as the breaking of a pipe or thefailure of supply of water, that renders it necessary to remove thewater back from the fire to prevent its being burned out or damaged, orwhenever the hot water is not needed such as on ironing days, and riskexists of a hot fire forming steam in the water back, and in the hotwater boiler causing it to collapse or splitting the back by the coldwater rushing in, then the water back is moved away from the fire asbefore explained and a soapstone or fire brick m, introduced.

The necessity for and ing from this movable water back will be morefully apparent from a reference to my aforesaid patent on which thepresent is an improvement. Difficulty arose in the handling of the firebrick or soapstone set forth the benefits resultin my said patent. Ihave therefore provided a metal frame at, to receive this soapstone orfire brick, and in order that it may set up closely to its place Iprovide a lug 0, on each side that has a curved upper surface, see Fig.3, that takes the side flanges of the frame 11., and causes the brick toassume the inclined position shown. water back are partially removed ornotched as seen in Fig. 2, to pass these lugs 0, 0. A handle is providedat the center of the upper edge of the frame at, by which the same maybe lifted out of or lowered into place. (See Fig. 3, at 11.)

The couplings 22, forming hollow faucet hinges on which the water backturns, are attached to a plate 1, on the range by a clamping nut 15, andthe plate 7", is slotted where the coupling is attached so that thewater back can be adjusted. The ends of each pipe 7', or g terminate ina thimble 13, ground into the socket 1 1, similar to a cock or faucetplug, and 12, is a screw coupling retaining the same in place. At thispoint the pipes f g and water back turn with facility, and the joint iskept perfectly tight, the socket 14 remaining stationary. Fig. 5 shows asection of one of these couplings p as in one plane: the sockets 14,passing through the The ends of the.

plate 7, and being attached thereto by the nuts 15, also receive thenecks 16, of the pipes g, g, for the circulating hot water to theboileras usual.

The advantages of my improved mode .of fitting water backs to ranges620. will be fully apparent, and the practical operation of the same hasbeen fully and satisfactorily tested.

hat I claim and desire to secure by Let- 'ters Patent isl. The movablewater back e, when sustained by the rollers 2, 2, and actuated by thelever h, and rod 2' as and for the purposes specified.

2. The arrangement of the movable plate Z, and finger 8, relatively withthe movable water back 6, for the purposes and as specified.

3. The hollow or faucet hinges (g), 7),) combined with a movable waterback whereby the said water back can be turned toward 1
